Abstract: Described herein are systems, methods and computer-readable media for maintaining a configurable project hierarchy. The method includes establishing a project hierarchy with multiple hierarchy levels including first and second hierarchy levels. The first level has an associated issue type. The method further includes receiving a request to change the hierarchy level of the first issue type to the second level. In response to receiving this request, the method includes: accessing from a data store, a hierarchy-issue type association record of the first issue type including an identifier of the first issue type and a current hierarchy level identifier; creating a new hierarchy-issue type association data record including the identifier of the first issue type and a new hierarchy level identifier corresponding to the second hierarchy level; and associating the first issue type with the second hierarchy level by storing the new hierarchy/issue type association data record in the data store.
